tuning is not working
Function Setting range
True: use the PID algorithm.
False: reset the output value (MV) to
0, and stop using the PID algorithm.
-32768~32767
0: Automatic control
When PID_MAN switches from True
to False, invoke the output value
(MV) in the automatic algorithm.
1: Auto tuning the parameters for the
temperature control. After tuning is
done, the system is in auto control
mode (PID_MODE is set to 0) and
fill in the appropriate parameters
(Kc_Kp, Ti_Ki, Td_Kd, Tf, APPHA
and BETA)
Note: when the mode is set to 1, auto
True: Manual
False: Automatic

Description
Target value
tuning the parameter, you
cannot set up the value.
Output the MV according to
MOUT. This setting has no
effect when PID_MODE is set to
1.
Output the MV according to the
PID algorithm.
MOUT value varies with the MV.
MOUT value does not vary with
the MV.
Auto tuning NOT
